Configuring BLU link Settings
The BLU link Settings menu is only available in BLU link CDi DriveCore models. From the
BLU link Settings menu (
), BLU link sample rate, clock priority, and outputs can
be configured.
To configure BLU link settings:
1�
From the Home screen, press the
MENU
button.
2�
Select the "BLU link" option from the menu using the
ENCODER
.
3�
Select the "BLU link Settings" option from the menu.
4�
Select the desired options for your application, making selections with the
ENCODER
.
5�
When done, select "Done" at the bottom of the screen.
Available options:
•
Sample Rate (48kHz, 96kHz)
Sets the BLU link sample rate in the amplifier. Sample rate can be set to 48kHz (default) or 96kHz. When set to 48kHz, the amplifier can access BLU
link channels 1-256. When set to 96kHz, the amplifier can access BLU link channels 1-128.
NOTE:
The sample rate must be set to match all other devices on the BLU link bus in order to pass BLU link audio.
NOTE:
The CDi DriveCore amplifiers process audio using a fixed 96kHz internal sampling rate. When using a BLU link sample rate of 48kHz, the
audio signal from the BLU link bus will be sample rate converted from 48kHz up to 96kHz when entering the amp, and any audio signals sent from the
amp back to the BLU link bus will be converted from 96kHz down to 48kHz.
NOTE:
If the amp is configured to use any BLU link channels between 129-256 and the sample rate is then changed from 48kHz to 96kHz, all BLU
link assignments above 128 will default back to an "unassigned" state since they will no longer be applicable at 96kHz.
•
Priority (0-254)
Determines which device on the BLU link bus will provide audio clock for the entire bus. The higher the value, the higher the priority. Under
certain conditions, such as when two devices have the same Priority settings, other factors may be used to determine BLU link clock priority
(see
for more information).
•
BLU link Output Channel 1-4* (Off, 1-254 @ 48kHz / 1-128 @ 96kHz)
The CDi DriveCore amplifiers are capable of outputting up to 2 channels (2-channel models) or 4 channels (4-channel models) of audio onto the BLU
link bus. These options allow you to assign the desired BLU link output channels. Channels 1-256 are available when using a 48kHz BLU link sample
rate and channels 1-128 are available when using a 96kHz BLU link sample rate.
•
BLU link Output Source 1-4*
These options allow you to select the source to route to each BLU link output channel, with the following options available:
• Analog Input 1-4
*
(routes the pre-processed audio signal from the input)
• Amp Output 1-4
*
(routes the same audio signal present at the amplifier outputs)
For information on routing BLU link channels to the amplifier's inputs, see
"Assigning Input Sources" on page 14
For information on configuring BLU link output settings in Audio Architect, see
"Configuring BLU link Outputs" on page 35
*
Channel 3 and 4 options available in 4-channel CDi DriveCore models only.
